I am a T4 paraplegic and I have been working on converting my 2016 Yamaha YXZ 1000 to hand controls. The link below is to the website where I am posting details on my build. For a paraplegic looking for ideas on how to convert to hand controls they may find it helpful. The link below goes to page 9 where I started posting the Yamaha YXZ 1000 build. I have not completed the build yet , I am still debugging it.
